AC 100V Horizontal Float Switch Liquid Water Level Sensor — reliable on/off level detection for aquariums, fish tanks and pools Why you need it Keeps water at safe, consistent levels to protect aquatic life and equipment. Automates pump control and refill systems so you do not have to monitor water levels manually. Helps prevent overflow and dryrun damage by providing a simple, dependable switching signal at the chosen level. Key benefits Simple operation: this horizontal float switch detects liquid level and provides an on/off signal for control of pumps, valves or alarms. Designed for AC 100V systems: ready to integrate with compatible controllers and equipment that use AC 100V. Versatile for common water applications: intended for use in aquariums, fish tanks and pools where horizontal mounting is preferred. Main attributes Functionality: horizontal float switch that changes state when the float reaches the installed level, enabling automated control or alarm functions. Compatibility: intended for systems and devices operating at AC 100V; suitable for use with pumps, relays and controllers rated for that voltage. Orientation and mounting: horizontal float design for placement at the desired liquid level; mounts in a horizontal position to detect rise or fall in water height. Performance: provides straightforward, mechanical on/off level detection for liquid level control. Typical use cases Aquarium water management: automate off or sump control to maintain a stable water level for fish and plants without daily manual checks. Fish tank safety: connect to pumps or alarm systems to prevent overflow or to shut off circulation if the water drops below safe levels. Pool auxiliary control: integrate with pool pump or refill systems to help maintain a target water level and protect equipment. What to expect A compact level sensing solution that offers simple, mechanical switching action when the float reaches the horizontal set point. Direct, easytounderstand behavior that makes it straightforward to wire into AC 100V systems through appropriate relay or controller interfaces. Installation and use tips Install the float switch horizontally at the liquid height where you want switching to occur. Verify that the connected equipment and wiring are rated for AC 100V and follow applicable electrical safety practices. Test operation after installation to confirm the switch activates at the desired level and that connected devices respond as intended. Notes Designed specifically for liquid level detection in aquariums, fish tanks and pools and for use with AC 100V systems. Use with compatible equipment and observe local electrical codes.
